I created my first ‘versioned’ AIX 5.2 WPAR on AIX 7 today. To get
me started, I followed the steps in the following guide from the AIX 7 Open
Beta On-line Information Centre: http://publib.boulder.ibm.com/infocenter/aix/v7r1/index.jsp?topic=/com.ibm.aix.cre/creconfig-create-wpar.htm In order to create the WPAR, I needed an AIX 5.2 mksysb file to
supply to the mkwpar command. Fortunately, I just happened to have an old AIX 5.2 mksysb image
in my archives! I then executed the following command to build the WPAR: # mkwpar -n wpar1... [More]

OK, it’s
official. The AIX 7 Open Beta is now available for testing! An
overview of the program is available here: https://www14.software.ibm.com/iwm/web/cc/earlyprograms/websphere/aix7ob/index.shtml Essentially
this program is designed to give IBM customers, ISVs and IBM BPs the

general availability. This is a great time to join forces and help IBM mould
the next generation of the AIX OS. I got

system I can run lsof and check
port 22 (SSH). Immediately I have a good idea of the existing SSH
sessions/connections. I can also check to see if the SSH server (sshd daemon)
is running and listening (LISTEN) on my AIX partition. # lsof -i tcp:22 Value of I :77 np:0 COMMAND... [More]

If you are
a system administrator that is responsible for managing AIX systems that run
SAP, then you’ve probably had an experience similar to the following? OK, so one
day my SAP Basis administrator contacts me and says “ I can’t start saposcol ......can
you please reboot the system? ” I quickly reply, “ Was there an error message when trying to restart saposcol ?”. He
replies, “ No ”. Again I return very
quickly, “ OK, have you checked to see if
there are any shared memory segments left for saposcol? ”. Just as quick, he replies “... [More]
